6 Claims.

This invention relates to taps for receptacles for liquids and more particularly to taps for barrels for holding beer and other beverages.

The main object of the invention is to provide a device of the above types embodying a separate closure member for the outlets of liquid receptacles which is of novel form and more convenient and economical than those commonly used. Another object is to provide a closure for such outlets which contains a breakable and removable element of new form and mode of application. A further object is to provide improved means for connecting the closure member with the draw off apparatus. Still another object is to provide a device of this class in which the breakable element is ruptured by means separate from the draw 01f pipe or rod.

The embodiment of my invention which I prefer to employ containing the above imp-rovements, together with other advantageous and novel features ofv my invention which will be hereinafter more fully described, is illustrated in the drawings accompanying and forming part of this specification, and in which,

Figure 1 is a central vertical section partly in elevation of one form of my improved tap for liquid receptacles.

Fig. 9 is an enlarged vertical section of a sealing member for use with the same.

Fig. 10 is a top plan of the sealing member, and

Fig. 11 is a bottom plan of the same.

Referring to Fig. 1 of the drawings, the numeral 2 indicates the wall of a liquid receptacle such as for instance the head of a barrel, and 3 is the outlet opening of the same. There is a closure member such as the ring 5 which is preferably screw threaded at 6 to engage a companion screw thread 4 in the opening 3. Preferably there is a fiange 1 on the ring 5 and there is a beveled part 8 on the lower side thereof and both of said parts are adapted to fit a recess 9 formed in the wall 2.

the closure member or ring The closure member or ring 5 is of nonrusting material and is provided with a bore Ill which bore has a reduced part indicated by H and a further reduced part iii. In said part I! is placed a suitable member such as the nipple [3 which is preferably of harder material than the ring 5 and also nonrusting. It is preferably held in said bore by placing it in position by what is ordinarily termed a forced fit so that it is securely held in the ring 5 and practically forms a part thereof. The nipple 53 preferably has a screw threaded outer part 84 and a bore such as l5 having a reduced portion l3. Between the main portion of the bore 55 and the portion I6 is a shoulder ll and in the lower part of the main portion I5 is a recess 58 preferably tapered as at Hi from the outer part inwardly and ending in a beveled groove 29, the bevel of which is joined to the shoulder H.

In the recess is of the nipple i3 is placed an annular sealing member such as 23, which consists of a portion 24 to cover the shoulder ll of the nipple I3, a portion 25 to cover the reduced portion iii of the bore l5, and a peripheral portion 26 preferably tapered upwardly or outwardly as shown and by means of which it is adapted to be held in the recess l8. When finally set in sealing position it has an upset bead or rim 2! which fits the groove 20. There is an annular element 28 of flexible material such as paper affixed to the bottom or inner side of the member 23 which is adapted to make the seal watertight.

There is a connection member or fitting 33 adapted to be placed over and secured to the member 5. Preferably there are coupling means such as the coupling sleeve 34 mounted on the connection member 33 and preferably turnable thereon. The said sleeve 34 has an internal screw thread 35 to engage the external screw thread l4 of the nipple l3 and also has thumb pieces 36 by which it can be turned. The sleeve 34 has a bore 31 and a reduced part 38 of the sleeve fits the outside of a short tube 39, screw threaded at 43 to secure it to the connection member 33 and also having a collar 4! to bear against the shoulder 42 of the sleeve 34 to hold it turnably on the tube 39. Inside of the tube 39 is a tubular cutter 43 having a sharpened lower edge 44, said cutter being securely fastened to said tube 39 and movable therewith and with the connection member 33. There are holes 45 for turning the tube 39 into and out of place. There is a collar 46 of rubber or similar material secured around the lower part of the cutter 43 and. adapted to press against the the top part of the sealing member 23.

' suitable receptacles.

passes through the stufling box thus preventtop or outer part of the sealing member 23, to hold the same more firmly when it is being perforated by the cutter 43.

The connection member 33 has a branch 48 which can be attached to a compressed air pipe such as the pipe 49. At the outer part of the member 33 is a stufiing box such as 50 having a screw threaded gland 5| and a packing 52.

The closure ring 5 having been inserted in the wall 2 of the receptacle, the latter is filled with the desiredv liquid and the sealing member 23 is placed. in the nipple I 3 in the shape shown in the dotted line position in Fig. 6. It is then secured in position in any suitable manner such as by driving it home by a suitable implement such as that shown for instance in Fig. 6. The

implement shown in said figure has a shank a, a head I), and a nose 0 having a rim or bead d conforming in shape to the groove 29 of the nipple '13. This implement having been brought down against the member I8, is given a blow with a hammer'or suitable tool and sets the sealing member 23 firmly in the recess l8 by expanding the peripheral portion 26 outward into the same. It is moved downwardly as well so that its upper edge 26' passes below the upper edge of the recess l8 and expanding outwardly is firmly caught under the same. The portion 26 is made a close fit in the bore l4 and thus a very slight expansion in its diameter is sufficient to hold it firmly in the recess 18.

When it is desired to remove the contents of the receptacle, the connection member or fitting 33 is secured to the closure member 5 by coupling it to the screw threaded part of the nipple I3 thereof by means of the coupling sleeve 34.-

When the sleeve34 is nearly at final downward position, the tubular cutter 43 will contact with Further movement of sleeve 34 will cause the cutter 43 to cut through the member '23 so that the contents of the receptacle can flow into the draw tube through the member 33 and thence into The draw tube or rod 54 ;ing spilling of liquid when pressure of air is brought into the receptacle on connection of the member 33 with the air pipe 49.

The sealing member 23 is preferably formed with a weakened portion such as 55 which will more readily'and surely give way to the cutter 43. The said portion 55 is annular and defined by the circular scoring 56 and is in fact almost broken through the sheet metal of which the member 23 is formed- The scoring is not a complete circle however but there is a narrow part 51 which is not scored. The said member 23 is further depressed inward at 58 toward the interior of the receptacle, so as to more readily give way and preferably there are indentations 58', ordinarily three in number which also assist to weaken this part togive way to the cutter 43. Thus the part55 will be more sure to move out of the opening in the member 23 but will 'hang by the portion 51 and the opening in said member will be practically clear to permit the passage of the contents of the receptacle into the connection member 33. When it is desired ;to remove the broken sealing member 23, this can be effected by a suitable implement such as a screw driver or the like through the slots 29 in the nipple I3,

In the form of the device shown in Fig. 7 the numeral'2' indicates the wall of aliquid receptacle and 3 is the outlet opening of the same.

There is a closure member such as the ring 5 screw threaded at 6' to engage the screw thread 4' of the opening 3'. The closure member 5' has a bore 60 which is internally screw threaded at 6! and said member also has a reduced part of the bore indicated by 62. In said part is placed a suitable member such as the nipple 63 and the latter is held in the bore a forced The nipple 63 preferably has a collar 64' rests on the shoulder 65 of the member 5". There means of which it is adapted to be held on the side 12 of the beaded part 66. The portion 7| is preferably made with corrugations such as 13 by means of which it can be crimped tightly onto the part 66. There is an annular part 14 inward of the portions 69 and 19 preferably made of flexible material such as paper.

On the inner side of the member 5' I have placed another closure member such as the check valve 16 which may be of any suitable form but preferably has a disk 11, a pivot support 18, a pivotal portion 19, a pivot 80 and a counterweight such as 8|. 7

There is a connection member or fitting 33 adapted to be placed over andsecured to the member 5'. Preferably there are coupling means such as the sleeve 34 mounted on the connectionv member 33' and preferably turnable thereon. The said sleeve has an external screw thread 35' to:

the same is being ruptured. The sealing'member 68 has scoring 56 and indentations 58" defining inwardly depressed part 58". It also has the part 51 corresponding to 51 in Fig. 4 and 69 refers particularly to the part over the seat on nipple 63.

The check valve 16 may be used with the sealing member of either form of the tap and when it is used the draw tube 54 or 54 must be'pusheddown through the stuffing box 50,0r 50' after the sealing member is broken through, so as'to open upthe check valve and permit passage of liquid. This also has to be done if for any reason the check valve is used without the sealing member.
